never had a problem with the hks ti exhaust I had on before the amuse ti exhaust either. I must add that both exhausts on the supra were pretty straight and didn't have much bends and welds as this m3 exhaust system.

The S2000 exhaust only had a few bends but like I said...

And I've never had any problems with any titanium exhaust systems on former cars and motorcycles.

I really think I am going to order this exhaust when I get next months paycheck, and get the blue the darkest hue of blue possible (I own an SSII)

I really likes the looks of this thing (with the headers)

Did you order from Bullet-proof, or did you order it straight from Japan?

I am already gonna guess that since there is no Canadian Distrubtor, and I will have to go the same you route you go, except with extra U.S.A to Canada costs.

If you can P.M with the details that would be great!

Well, I definately don't have a source for the Amuse #s but I was just trying to say that the full exhaust system would probably be louder than a Eisemann race (which is abt 102 db). I just threw a random # out there just to make my point that the Amuse would probably be louder than the RACE considering its a full-exhaust system. The #s are greatly affected by where the sound is measured, and I suppose that Eisemann did not measure this 102db from the cabin and windows up. Therefore, being a sports/luxury car, the "110db" from outside would definately not translate to such a high level inside the cabin.

I don't know what the #s for the Kreissig exhausts are, but I can tell you with a straight face that those probably do over 110+db (measured from outside)

And btw, the threshold of pain is 130db (http://www.glenbrook.k12.il.us/gbssc...nd/u11l2b.html)

Lastly, if you are judging an exhaust's volume based on youtube videos, I can tell you first-hand those videos don't do any justice. Even when Nate from IND posted high quality vids for the Eisenmann Race, the thing still sounded much louder in real life.

Well Im not an expert but I do use logic and common sense pretty well. Straight pipe exhausts are generally the loudest right? Look at the amount of bends on the exhaust in the pic on the previous page. Notice also the giant cannisters. Add in the fact that it retains both sets of cats. And you think it will be super loud?

The Eisenmann Race is only a cat-back system and it already generates a little more than 100db. Until Amuse releases some actual #s, we all are just making predictions. Hopefully someone can get their hands on this thing soon and give us their opinion.

I've owned a street car louder then that. But that was only when the waistgate was open.

A car as loud as a cupcar for the street would get old fast...

I'm not sure if you guys have had a chance to check out the new release from Vorsteiner. It is a similar style Titanium tipped exhaust for the E92 M3 and will be available for production and ordering within the next few weeks. Compared with Amuse's pricing, this exhaust is well worth it as well.

1yr warranty means they have no confidence in their product. Minimum 4 years for that kind of cash.
